Expert writing Tips
Best practice
Always use the base form of the verb after "did not". The correct form is "did not use". For example: "I "did not use" the old software version."
Common error
Avoid using the past participle form of the verb (e.g., "used") after "did not". The auxiliary verb "did" already indicates past tense, so the base form of the verb should follow. Instead of "did not used", write "did not use".
